It extends from (region T) to the line connecting the toe-side end portion Q of the outer side side portion 6 and the heel-side end portion S of the outer side side portion 6. That is, in the foot cover 100C, each low expansion / contraction portion 9 arranged on each of the side side portions 5 and 6 is connected by the sole portion 4.
  • the low expansion / contraction portion 9X As described above, it is possible to increase the tensile force on the heel portion 3 as compared with forming the low expansion / contraction portion 9X only on the inner side side portion 5 and the outer side side portion 6. ..

Further, the strong expansion / contraction portion 12 may reach the sole portion 4. It is preferable that the region of the strong expansion / contraction portion 12 is large because the surface in close contact with the heel becomes large. For example, the strong expansion / contraction portion 12 may be provided in a region from the sole portion 4 side to a height of about half in the foot height direction of the heel portion 3.
  • the foot cover 100C is provided with a strong expansion / contraction portion 12 at least a part of the heel portion 3.
  • the strong stretchable portion 12 is stretched by applying a tensile force to the strong stretchable portion 12 by the low stretchable portion 9X.
  • the strong expansion / contraction portion 12 generates a contraction force, it sticks to the wearer's heel.
  • the foot cover 100C can more preferably suppress the displacement / detachment than the configuration including only the low expansion / contraction portion 9X.
  • the heel part 3 is a place that receives a particularly strong impact when walking, and is easily rubbed by shoes. Therefore, in order to follow the movement of the skin of the foot F and the foot F, the heel portion 3 is preferably formed of a fabric having strong elasticity rather than a fabric having low elasticity.
  • the strong expansion / contraction portion 12 may be provided on a part or the whole of the toe portion 2. In this case, both the toe portion 2 and the heel portion 3 are pulled by the low expansion / contraction portion 9X and come into close contact with the foot F, so that the occurrence of displacement / detachment of the foot cover 100C can be more effectively suppressed.
  • the parts other than the low expansion / contraction portion 9X and the strong expansion / contraction portion 12 of the heel portion 3 are formed of normal fabric, but in the foot cover 100C, all the portions (main body 1) other than the low expansion / contraction portion 9X are formed. It may be a strong stretchable portion 12 having strong stretchability.
  • And 30/75 FTY may be used for the back thread to form a portion other than the low expansion / contraction portion 9X.

  • a portion other than the low expansion / contraction portion 9X may be formed by using one of 32 / -polyester cotton yarns and 40/75 FTY for the back yarn. This makes it possible to manufacture the foot cover 100C in which the portion other than the low expansion / contraction portion 9X is made of a fabric having strong elasticity.
  • the low expansion / contraction portion 9X is formed on both sides of the side side portion 5 and the side side portion 6 and is connected by the sole portion 4.
  • both the toe portion 2 and the heel portion 3 can be pulled from a wide area near the center in the foot length direction, so that the adhesion of the foot cover 100C to the foot F can be improved. ..
